For enhanced safety, the front and rear seat shoulder belts of the Toyota Prius have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Kia Niro doesn’t offer pretensioners for its rear seat belts.
The Prius has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Niro doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
Over 200 people are killed each year when backed over by motor vehicles. The Prius offers an optional Parking Support Brake that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Niro doesn’t offer backup collision prevention brakes.
The Prius has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Niro doesn’t offer all-wheel drive.
The Prius Limited offers an optional Panoramic View Monitor to allow the driver to see objects all around the vehicle on a screen. The Niro only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.
The Prius has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. Only the Niro LXS/LXS SE/Touring SE/EX Premium offers a blind spot warning system.
To help make backing out of a parking space safer, the Prius has standard Rear Cross Traffic Alert to warn the driver of approaching traffic and automatically engage the brakes to help avoid a collision. Only the Niro LXS/LXS SE/Touring SE/EX Premium offers rear cross-path warning.
The Prius has standard Safety Connect™, which uses a global positioning satellite (GPS) receiver and a cellular system to help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Niro doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the Prius and the Niro have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.
For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the Prius its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 36 vehicles tested by the IIHS. The Niro has not been fully tested, yet.
